Among the principal objects which the present invention has in view are: to cheapen the cost of construction of a shank iron; and to increase the capacity production of said irons.

In the drawin s:

Figure 1 is a at side view of a metal bar used in the construction of shank irons of the character mentioned.

Figure 2 is a cross section of the same.

Figure 3 is a flat side view of said bar after same has been prepared for the operation dies calculated to extract the' shank iron therefrom, the broken lines indicating the 16 outline of the shank irons when formed.

Figure 4 is a fiat side view of a shank iron for shoes, constructed and arranged in accordance with the method herein disclosed.

Description:

Heretofore, shank irons have been made in various ways, principally and preferably from sheet steel shaped or cut from the sheet and sub uently re nforced with ribs pressed therein. urther, it has been found expedil ent or necessary to employ dies for this purpose rerpliiring a large expenditure of manual and big paid labor.

When pursuing the present method, hand labor is largely eliminated, the work being 7 performed rapidly and accurately by -machines. I a

As seen best in Figure 1' of the drawings, bars 8 are hot rolled and shaped substantially as seen in Figures 1 and 2 of the drawings, and are then annealed. These bars have a uniform and known chemical content. They are rovided' with a plurality of ribs 9, the num r and design 0 which, however, may 'be changed at the will of the manufacturer. 40 The ribs 9 reinforce the resistance of the bars to bending strains incident to the weight of the individual in walking. When the shank having the ribs 9 is installed in a shoe, the ribs 9' are dependent from the body thereof. The bars 8, are flattened and spread at intervals to form the areas 10 with a conse- 'quent de ressing of the ribs at these intervals. Suisequently, they are operated upon by dies that bend and cut the metal to shape conforming substantially with the broken lines in Fi re 3 of the drawings. The shank \irons are on tempered to suit.

In the article thus produced, a shank head 11 is formed at one end of the shank iron, while a heel plate 12 is formed at the other. 5 The chemical content of the metal being constant, it is evident that a uniform quality will be found in all shank irons thus constructed.

It is obvious that the gang arrangement of the bar -8 during the formation of the shank 6O irons reduces materially the manual or hand labor which heretofore has been required.

I claim:

1. A method of constructing shank irons for shoes consisting in producing elongated flat metal bars having a reinforcing rib on 1 one side thereof; then pressing said bar at specified intervals to extend the same laterally and to depress the rib at such lateral extensions; then cutting shank irons of desired shape from the bar, the flat terminals of'said irons being cut from the flattened portions of said bar.

2. A method of constructing shank irons for shoes consisting in heating and rolling hot elonfited flat metal bars-of desired width and thic ess having a plurality of continuous ribs raised thereon in spaced relation; then annealing said. bars and then rolling cold said bars to uniform thickness and to flatten out and extend laterally said bars and ribs thereon at specified intervals to form sections from which may be cut the heads and heel plates of the shank irons; then die as cutting from said bars the shank iron, the widened head and flattened heel plate of said irons being severed fromv the flattened portions of said bar.

3. A method of constructing shank irons for shoes consisting in producing a flat metal bar having at regular intervals widened flattened sections and a raised rib between said sections; then severing said bar to form shank irons, the terminals of said shank irons being formed out of said flattened portions of said bar.

4. A method of constructing shank irons for shoes consisting in producing a flat metal bar having at regular intervals widened flattened sections, and a plurality of raised ribs between said sections; then severing said bar to form shank irons, the terminals of said shank virons being formed out "of said flattened pottiow of said bar.
